Type 2 inflammatory diseases: a new pattern of Group 2 innate lymphoid cells-dendritic cells-T helper 2 cells and advances in targeted drug therapies / 中华实用儿科临床杂志

In recent years, the discovery of Group 2 innate lymphoid cells(ILC2) has expanded the understanding of type 2 immunity and promoted the birth of the concept of type 2 inflammation.Type 2 inflammation is an inflammatory reaction mediated by both innate and adaptive immunity.It is mainly involved by ILC2 cells and T helper 2 cells and is characterized by upregulation of type 2 cytokines and IgE-mediated release of inflammatory mediators and barrier dysfunction.Due to the common intrinsic mechanism, several kinds of type 2 inflammatory diseases always coexist in the same person, and their prevalence rate and severity continue to rise among children and adolescents, placing a heavy burden on them and their families.This review summarizes the recent development in understanding the mechanism of type 2 immune response and the pathophysiological mechanism of type 2 inflammatory diseases, emphasize the importance of ILC2 and summarize some targeted biologics used in the treatment of related diseases, so as to have a more systematic, comprehensive and in-depth understanding of type 2 inflammation.

The Relationship Between Religious Beliefs and Related Factors and Psychiatric Symptoms in Adolescents: A Cross-Sectional Secondary Analysis of Data From NIPHEAC, 2020

Objective@#This study aimed to explore the psychiatric symptoms and associated risk and protective factors among religious adolescents after 2-month home confinement against coronavirus disease-2019 (COVID-19) in China. @*Methods@#11,603 Chinese adolescents in grades 7–9 were recruited in this survey. An online survey was designed to collect the data. Participants were measured using the Patient Health Questionnaire-9 and Generalized Anxiety Disorder-7 Scale. @*Results@#Religious adolescents showed significantly more severe depressive and anxiety symptoms compared to non-religious. 249 (2.2%) reported COVID-19 exposure. Logistic regression analysis revealed that religiosity was a risk factor for the symptoms of depression (p=0.001) and anxiety (p<0.001). Moreover, among those adolescents with religious beliefs, psychological resilience was protective in preventing depressive and anxiety symptoms. At the same time, emotional abuse, emotional neglect, and a poor parent-child relationship were risk factors. @*Conclusion@#Our finding indicates that religious adolescents easily develop depressive and anxiety symptoms, compared to non-religious adolescents. Moreover, those with emotional abuse, emotional abuse, and poor parent-child relationships are more likely to suffer from mental distress and should pay more attention to cope with their mental health.

Clinical application of thromboelastography in the prevention of lower extremity intermuscular venous thrombosis after knee arthroscopy / 中国输血杂志

【Objective】 To explore the guiding value of thromboelastography (TEG) in the formulation of personalized anticoagulation regimen after knee arthroscopy. 【Methods】 A total of 50 patients who underwent knee arthroscopy in our hospital from April to August 2023 were randomly divided into two groups. Twenty-seven patients with routine anticoagulation were selected as the control group, and 23 patients with personalized anticoagulation were selected as the experimental group. Conventional anticoagulation was a prophylactic dose of low molecular weight heparin calcium (LMWHC) selected according to body weight, once a day to 7 days after surgery. Personalized anticoagulation was performed according to the prophylactic dose of LMWHC until postoperative day 3. On postoperative day 3, LMWHC was changed to aspirin according to the TEG return index (MA>70 mm, α Angle >72°, K value <1 min), and the initial prophylactic dose was 100 mg/d. LMWHC was changed to rivaroxaban when R<5 min, and the prophylactic dose was 10 mg/d until postoperative day 7. Patients with hypocoagulation or subcutaneous ecchymosis stopped the drug first, and if it was further aggravated, component blood transfusion was performed according to the TEG results. The difference of Caprini score in perioperative period, the correlation between TEG and CCT on postoperative day 1, and the accuracy of predicting thrombosis on postoperative day 7 were compared between the two groups using the receiver operating characteristic curve (ROC). 【Results】 There was a significant difference in Caprini score between the two groups at 7 days after operation (P<0.05), suggesting that the adjustment of anticoagulant drugs in the experimental group was effective at 3 days after operation. Pearson correlation evaluation showed that there was a strong positive correlation between maximum coagulation intensity (MA) in TEG and platelet (Plt) in CCT at day 1 after surgery (P<0.05). Thrombosis was found in the control group at 7 days after operation, all of which were CMVT and disappeared after therapeutic antithrombotic therapy. MA was included in the ROC curve for model analysis. The area under the ROC curve (AUC) of the control group was 0.819, and the AUC of the experimental group was 0.508. It was found that the control group model had higher accuracy in predicting the formation of CMVT. 【Conclusion】 Individualized anticoagulation under TEG monitoring can effectively reduce the occurrence of CMVT after knee arthroscopy, which has guiding value for anticoagulation and thrombosis prevention.

Practice of precise management of antibiotics in a children′s hospital in combination with key performance indicators / 中华医院管理杂志

Bacterial infection is the main cause of infectious diseases in children. Antibacterials play an important role in anti infection treatment of children. At present, the treatment of antimicrobial drugs in children is facing a severe situation of bacterial resistance. In January 2020, a children′s specialized hospital carried out the practice of precise management of antibiotics in combination with key performance indicators. Through the multi sectoral linkage of management and technology, eight key performance indicators and assessment methods were set up from three levels of antibiotic use, bacterial resistance and hospital infection, to standardize the clinical application of antibiotics and continue to promote the rational use of antibiotics. This practice had improved the performance indicators of antibacterial management. Among them, the use intensity of antibacterial drugs for inpatients decreased from 40.07 DDD in 2019 to 29.00 DDD in 2021, the use rate of antibacterial drugs for inpatients decreased from 81.32% to 64.40%, the percentage of antibacterial drug expenses in total drug expenses decreased from 35.41% to 26.82%, the use proportion of non restricted antibacterial drugs in antibacterial drugs increased from 71.30% to 82.21%, and the drug resistance rate of Salmonella to β-Lactam/enzyme inhibitors decreased from 4.84% to 0.03%, and the incidence of hospital infection decreased from 1.16% to 0.96%. The precise management of antibiotics in combination with key performance indicators improved the level of rational use of antibiotics, effectively curbed bacterial resistance, achieved phased results, so as to provide a reference for the scientific management of antibiotics in children′s hospitals.

Clinical and genetic analysis of a child with early-onset severe obesity / 中华医学遗传学杂志

OBJECTIVE@#To explore the clinical phenotype and genetic etiology of a child with early-onset severe obesity.@*METHODS@#A child who presented at the Department of Endocrinology, Hangzhou Children's Hospital on August 5, 2020 was selected as the study subject. Clinical data of the child were reviewed. Genomic DNA was extracted from peripheral blood samples of the child and her parents. Whole exome sequencing (WES) was carried out on the child. Candidate variants were verified by Sanger sequencing and bioinformatic analysis.@*RESULTS@#This child was a 2-year-and-9-month girl featuring severe obesity with hyperpigmentation on the neck and armpit skin. WES revealed that she has harbored compound heterozygous variants of the MC4R gene, namely c.831T>A (p.Cys277*) and c.184A>G (p.Asn62Asp). Sanger sequencing confirmed that they were respectively inherited from her father and mother. The c.831T>A (p.Cys277*) has been recorded by the ClinVar database. Its carrier frequency among normal East Asians was 0.000 4 according to the 1000 Genomes, ExAC, and gnomAD databases. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), it was rated as pathogenic. The c.184A>G (p.Asn62Asp) has not been recorded in the ClinVar, 1000 Genomes, ExAC and gnomAD databases. Prediction using IFT and PolyPhen-2 online software suggested it to be deleterious. Based on the guidelines from the ACMG, it was determined as likely pathogenic.@*CONCLUSION@#The c.831T>A (p.Cys277*) and c.184A>G (p.Asn62Asp) compound heterozygous variants of the MC4R gene probably underlay the early-onset severe obesity in this child. Above finding has further expanded the spectrum of MC4R gene variants and provided a reference for the diagnosis and genetic counseling for this family.

Isoliquiritigenin inhibits mouse S180 tumors with a new mechanism that regulates autophagy by GSK-3ß/TNF-α pathway.

In this study, the pharmacokinetic properties and stability of isoliquiritigenin (ILQ) in microsomes were evaluated. The data showed ILQ administrated by i.h had high absorption degree (absolute bioavailability> 90%), and strong elimination ability (average t1/2≈ 67 min). ILQ in rat tissues could reach peak at 0.25 h, and be detected in almost all tissues. In vitro, stability of ILQ in four species liver microsomes were rat > beagle dog > monkey > human > mouse. On the basis of pharmacokinetic (PK) profiles, mechanism of ILQ against S180 was explored. ILQ could not inhibit S180 growth directly in vitro. However, ILQ extremely prohibited S180 tumor volume in vivo. And when TNF-α in NK cells was knocked down by siRNA, ILQ had no inhibiting effect on S180 tumor. ILQ enhanced TNF-α expression in NK cells by FCM detection. Autophagy-associated proteins LC3-II, Beclin-1, ATG-7 were elevated in S180 cells co-cultured with ILQ treating NK cells. When TNF-α was knocked down by siRNA, ILQ could not induce autophagy in S180 tumors. In the NK cells of osteosarcoma patients, TNF-α was negatively correlated with GSK-3ß by ELISA detection. ILQ could inhibit GSK-3ß expression and further increased p65 and c-Rel expression in NK cells. When GSK-3ß was knocked down by siRNA, ILQ did not affect p65 and c-Rel expression. ILQ directly inhibited GSK-3ß and then activated the NF-κB pathway to enhance TNF-α expression in NK cells, which could induce autophagy in sarcomas. The present study supplied a new mechanism for ILQ against tumors.

Objective To determine the epidemiological and etiological characteristics of hand，foot，and mouth disease （HFMD） in Pujiang County from 2008 through 2020， so as to provide scientific evidence for prevention and control measures. Methods Descriptive epidemiological analysis was used to analyze HFMD cases retrieved in the Chinese Information System for Disease Control and Prevention in Pujiang County during 2008‒2020. Results From 2008 through 2020， a total of 9 393 cases were documented in Pujiang County， with an annual incidence of 182.3 per 100 000， showing a trend of alternating high-incidence and low-incidence years. The seasonal distribution was bimodal， and the incidence peaked in May-July and November-December. The incidence of HFMD in urban areas was significantly higher than that in rural areas， and the incidence was positively correlated with population density. Majority of cases （94.9%） were children under 5 years old， of which boys had higher incidence than girls. The number of documented cases was the highest among preschool children living in families and kindergartens， accounting for 97.3%. Totally， 558 cases were laboratory confirmed in Pujiang County in 2008-2020， of which severe cases were all caused by EV71 infection. Conclusion Enterovirus serotypes in HFMD have continually changed from 2008 through 2020 in Pujiang County. However， severe HFMD remains principally attributable to EV71 infection， suggesting that it is necessary to strengthen the surveillance on the etiology of HFMD. In addition， it warrants further promotion of EV71 vaccination.

Ocular surface flora in obese patients before and after dietary intervention / 中华内分泌代谢杂志

Objective:To investigate the changes of ocular surface microbiota in obese patients before and after dietary intervention.Methods:From November 1, 2020 to May 1, 2021, 35 obese patients in the obesity management center of the Department of Endocrinology and Metabolic Diseases of Henan Provincial People′s Hospital were selected for a 4-week low-calorie dietary intervention of 1 600-1 800 kcal/day. The body weight, body mass index(BMI), body composition(body fat, body fat percentage, visceral fat grade, total body water, and skeletal muscle) were observed before and after dietary intervention. The characteristics of ocular surface flora in obese patients before and after intervention were analyzed by 16S rRNA sequencing.Results:The body weight, BMI, body fat, percentage of body fat, visceral fat grade and total body water decreased significantly after 4 weeks( P<0.05), while there was no significant difference in skeletal muscle( P>0.05). There was no significant difference of ocular surface flora α and β in diversity( P>0.05). Opportunistic pathogens Pseudomonas and Cutibacterium decreased significantly, while Faecalibacterium, Lachnospiraceae NK4A136 group, Oscillospiraceae UCG 002, and Blautia, which producing short chain fatty acids, increased significantly( P<0.05). Functional prediction analysis showed that the metabolic pathways such as degradation related pathways and insulin signaling pathways of volatile organic compounds(VOCs) were significantly enriched. Conclusion:After dietary intervention, opportunistic pathogenic bacteria decreased and short chain fatty acid producing bacteria increased in obese patients. The altered ocular surface flora may be related to the degradation of VOCs and the improvement of insulin sensitivity.

Objective:To investigate the optimal monochromatic level for evaluation of in-stent lumen after transjugular intrahepatic portosystemic shunt (TIPS) by dual-layer detector CT.Methods:Twenty-nine patients after TIPS were retrospectively enrolled who underwent abdomen enhanced examinations with portal venous phases by a dual-layer detector CT between December 2019 and July 2021. The mixed iterative image (conventional group) and monochromatic images (40 keV group, 50 keV group, 60 keV group and 70 keV group) were obtained by reconstruction. Circular regions of interest were placed in the in-stent of the cross-sectional reconstructed image and in the vertical spinal muscle on the same plane to obtain the corresponding average CT value and noise. The contrast to noise ratio (CNR) and signal to noise ratio (SNR) were calculated. Then 4-point scale was performed to evaluate image quality subjectively by 2 physicians blindly and separately. One-way ANOVA or Kruskal Wallis H rank-sum test was used for the overall analysis between groups, and LSD test or Dunn′s Bonforoni test was used for pairwise comparison within groups. Results:There was no significant difference in noise values among the 5 groups ( P>0.05). The difference of CNR and SNR between the 5 groups was statistically significant ( F=72.28, 56.45, P<0.001). The CNR and SNR in the 40 keV group were the highest, which were 50.4±15.7 and 59.3±18.4 respectively, and the difference was statistically significant ( P<0.001). Subjective scores showed statistically significant differences among the 5 groups (χ2=101.61, P<0.001). The score of the 40 keV group was higher than that of the 60 keV group, 70 keV group, and conventional group ( P<0.001), and there was no significant difference when compared with the subjective score of the 50 keV group ( P>0.05). Conclusions:The 40 keV monochromatic image of dual detector spectral CT is the best image to observe the lumen of the stent after TIPS.

Clinical application of autogenous adipose-derived stromal vascular fraction-assisted fat transplantation in the improvement of facial skin quality / 中国组织工程研究

BACKGROUND: Many studies have shown that cell-assisted lipotransfer promotes the survival of fat implants, but there are few studies exploring stromal vascular fraction (SVF) -assisted fat transplantation for improving facial skin quality. OBJECTIVE: To evaluate the clinical effect of autologous adipose-derived SVF-assisted autologous fat transplantation in the improvement of facial skin quality. METHODS: From September 2016 to June 2018, in the Plastic and Cosmetic Center, the Affiliated Hospital of Xuzhou Medical University, 20 patients were recruited and then randomly divided into experimental group and control group, namely SVF-assisted fat transplantation and simple fat transplantation, respectively. A VISIA skin detector was used to detect facial skin quality of patients preoperatively and 6 months postoperatively, including spots, wrinkles, texture, pores, ultraviolet spots, brown spots, couperose skin and porphyrin. RESULTS AND CONCLUSION: The effect of improvement in wrinkles and texture in the experimental group was better than that of the control group, and the difference was statistically significant (P < 0.05). In terms of spots, pores and couperose skin, the therapeutic effect in the experimental group was better than that in the control group, but the difference was not statistically significant (P> 0.05). There was no significant difference between the two groups in the improvement of ultraviolet spot and brown spots. The porphyrin was not affected by the subjects. To conclude, SVF can promote the effect of fat transplantation in the improvement of facial skin quality.
